Walkthrough

A new command-line interface for generating videos using the CogVideoX model has been introduced, featuring a comprehensive script (text_to_image_cog.py) and a detailed README. This enhancement allows users to create videos from prompts with optimizations for performance and resource management, facilitating accessibility through clear instructions and structured functionality.

Changes

File	Change Summary
`onediff_diffusers_extensions/examples/cog/...`	Added a `README.md` with instructions for running `text_to_image_cog.py`, detailing command-line usage, model settings, and compiler configurations. Introduced `text_to_image_cog.py` for video generation, encapsulating functionality in `CogVideoGenerator` with methods for prompt encoding, warm-up, and video generation.

Poem

In the garden where ideas bloom,
A script was born to chase the gloom.
With prompts aflutter and videos bright,
A rabbit's dream takes wondrous flight! 🐇✨
Let the CogVideo spin and sway,
As we hop along this joyful way!

Tips

Chat

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>.
- Generate unit testing code for this file.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
- @coderabbitai generate unit testing code for this file.
- @coderabbitai modularize this function.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- @coderabbitai generate interesting stats about this repository and render them as a table.
- @coderabbitai show all the console.log statements in this repository.
- @coderabbitai read src/utils.ts and generate unit testing code.
- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
- @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Early access features: disabled

We are currently testing the following features in early access:

Anthropic claude-3-5-sonnet for code reviews: Anthropic claims that the new Claude model has stronger code understanding and code generation capabilities than their previous models. Note: Our default code review model was also updated late last week. Please compare the quality of the reviews between the two models by toggling the early access feature.

15-28: Consider making fps configurable.

The default fps is set to 8, which might not be suitable for all use cases. Consider allowing the fps to be configurable through the command-line arguments.

30-80: Simplify the default prompt for better usability.

The default prompt is very detailed and specific. Consider simplifying it to make the tool more approachable for new users.

88-155: Class design and implementation look good.

The CogVideoGenerator class is well-structured and flexible, supporting optional compilation and quantization.

157-193: Main function implementation looks good.

The main function effectively orchestrates the video generation process, providing clear output and resource usage information.

Add missing import for tempfile.

The tempfile module is used in the export_to_video_imageio function but is not imported, leading to a runtime error.
